is black mold causing my husband's illness in dubai?« Back to Previous Page

Persistent cough and headaches alongside visible black mould growth from an AC leak are strongly correlated. The constant humidity and year-round AC use in Dubai create an ideal environment for mould, and prolonged exposure to its spores is a common irritant that can cause exactly these symptoms, particularly in individuals with sensitivities or existing respiratory conditions.

For a situation involving illness and a long-term leak, a professional inspection is strongly advised. In Dubai, remediation companies should follow standards like the IICRC S520 for mould removal. The process isn't just wiping away the visible spots; it requires identifying the moisture source (the leaking AC unit), isolating the contaminated area to prevent spore spread, safely removing affected porous materials like the carpet and skirting board, and HEPA vacuuming and cleaning the entire zone.

Proper testing is key to confirming the type and extent of contamination. An air quality test or surface sample sent to an accredited microbiology lab can identify the species present and provide a concrete basis for the remediation plan. The AC unit itself will also need a full internal cleaning by an HVAC specialist to prevent recontamination.

Your first step is to stop the moisture source—have an AC technician repair the leak immediately. Then, contact a certified mould assessment professional who can provide a verified, lab-based diagnosis and scope of work for remediation.
